eof_detected status flag.  Delete is_eom and is_eof methods.
	Move drive_size, bytes_per_sector, eom_detected status flag, as well
	as the methods read_file, write_file, raw_read and raw_write to ...
	(class fhandler_dev_floppy): ... here. Remove is_eom and is_eof
	methods.  Add dup method.
	* fhandler_floppy.cc (IS_EOM): New macro.
	(fhandler_dev_floppy::is_eom): Remove.

	(fhandler_dev_floppy::ioctl): Move blocksize check in RDSETBLK case
	to here.
	* fhandler_raw.cc (fhandler_dev_raw::is_eom): Remove.
